RED SCAFFOLD AREA RECCO. (1) Ranch in center N½, sec. 34 T. 11 N., R. 18 E., Ziebach Co. I Hill between stockdem west of Ranch and Ranch house has few Timber Lake concs with P. linguiformis fauna. At Stockdem "barron" concs above bentonite had part of a D. nebrascensis. General section is obscure, but seems to be silty shale some Sud streaks, with light grey, with at least 1. bentonite near lower part; those beds contain brown weather concs, some with yellow cclc., chiefly barron. Above or at top are a few with T.I. fauna, below dk pierre-hke shale with rb + light weather barron cclc.? concs. (Latter exp. in Red Scaffold Cr. at crossing in sec. 5, T. 10 N., R. 18 E.) Apparently divides in much of headwater areas of Beaver and Red Scaffold Creeks are underlain by Timber Lake equivalent. Numerous concs locally but ones in Sec. 33, T. 11 N., R. 18 E. are ones we got westernmost fauna from. Deserves further tracing westward. 32
